When my full-size headphone was snapped in half several years ago, I was scrambling to find a new one. I got a newer similar model from a local store for around $20 - but then after several months, its cable broke and became basically a mono headphone. A friend of mine then gave me a KOSS portaPro. The portaPro is an on-ear headphone, which I have never used before - since all of my headphones were always full-size ones. So understandably, I was very skeptical about it. But since my banged-up mono broken headphone was my only other option so I started using it. It has been about 3 years now since I started using the portaPro - and I am still using it as my trusty headphone.
Awesome sound!I still distinctly remember when I used it for the first time to listen to music (prior to that I was using it for listening to podcast), I was really blown away. The sound quality coming out from this seemingly dinky headphone is amazing. Yes, my old full-size headphones were cheap (less than $40) and obviously not BOSE or Beats or any of those fancy ones. But seriously, this portaPro was awesome in terms of sound quality. Clear and powerful bass, superb mid-range, balanced treble. I would say that the sound quality of this portaPro probably competes with the mid-range ($75-$150) full-size headphones (with no noise-cancelling).
Cheap!Since the portaPro was a gift, I did not know how much it cost - so I looked it up online on Amazon - and it was cheap (or at least A LOT cheaper than those fancy headphones). It is only about $45 (or less) - which is only 1/4 of the price of Beats ($199), 1/7 from Bose ($299), or 1/2 of any typical Sony headphones (~$100). Then you say it's because it's an on-ear, of course it's cheap. Yes, that might be true - but, I have tried other on-ear headphones (Logitech, Sony, Panasonic, Phillips) and none of them rival the sound quality of the portaPro. Truly, I think the combination of the sound quality and the economic price hits the sweet spot for me.
Small sizeThe advantage of having the portaPro vs a full-size headphone is the small size. It fits easily into my laptop bag, my travel bag, or even my wife's purse. This is something I could not do with my full-size headphone - which means if I decide to carry it, I practically have to have it hanging on my neck all the time if not using it. The portaPro also folds - makes it even smaller.
Last longer than my older headphones
After 3 years, I had to replace the foaming pads that cover the drivers. The old foaming are torn. I bought the foaming on Amazon and they install easily - just remove the old foaming, put new ones one - took about 3 minutes and done. No glue, no stitching, no hassle.
Now it feels like it's a new headphone again.
So if you are in the market for a headphone, I suggest you check out KOSS portaPro. I totally love mine and I am guessing you will be pleasantly surprise by it.
